Video of Race in hub

Hello everyone. I am almost done with my rebuild (R90/6), and discovered that a race was loose on the front hub. Video enclosed. Are there any sleeving options, or oversized bearing options, or is this just scrap now...

There are Loctite products that are designed for something like this. The "Green" formulation comes to mind.

This has been a topic covered many times over the years and there are many fixes out there. Perhaps now would be time to delve into Snowbum's writings to see what he has to say about the issue? LOL, I am sure he has covered it. Good luck, St.

Great advice already provided. Apparently, excessive bearing preload from improper shimming or excessive axle tightening is the culprit.
Is the race in the video new or from the spun bearing?
Try this method.

Special trick on how to seat a loose bearing race
Here, you will need a center punch, a hammer, and Loctite 660.

With the old race out, take a center-punch, and strike the inner surface of the housing (the point where the side of race meets too).
Repeat the above procedure on the circumference of the opening. The process displaces some metal by pushing it above the current surface resulting in some bumps. The effect is the reduction of the diameter of the housing opening and restoration of the friction fit. But that is just the first part.
To ensure that your race remains in place, apply a film of Loctite 660. The film can help to lock two components together in places where there is a gap of 0.020 inches.
Now that the Loctite is applied, carefully use a driver to seat the race in the usual method. You also need to allow ample time for the compound to bond. The combination of the two types of treatments should be adequate to leave the race secure and ready for optimal performance.
